            Bug ID: 26090
           Summary: Incorrect exclude.exp
           Product: binutils
           Version: 2.35 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
  Target Milestone: ---

exclude.exp has

if { [ld_link $ld tmpdir/exclude.so "--exclude-libs libexclude.a --shared
tmpdir/exclude1.o -Ltmpdir -lexclude"]
     && [ld_nm $nm "-D" tmpdir/exclude.so]
     && ! [info exists nm_output(exclude_common)]
     && ! [info exists nm_output(exclude_sym)] } {
    pass $test5
} else {
    fail $test5
}

tic6x-elf has

  ret->elf.is_relocatable_executable = 1; 

 /* True if this target has relocatable executables, so needs dynamic
     section symbols.  */
  bfd_boolean is_relocatable_executable;

"nm -D" reports:

02001380 B _HEAP_MAX
00001380 B _HEAP_START
02101380 B _STACK_START
0000137c b exclude_common
0000126c D include_sym
FAIL: ld exclude symbols from archive - --exclude-libs libexclude

It is wrong to check if exclude_common is in the dynamic symbol table
without checking its binding.
